Description
Summary:In this paper, implementation and performance comparison of five control methods for the average-current-controlled three-phase six-switch boost PFC rectifier are presented. The considered average-current-control methods include implementations with three independent controllers, with six-step PWM, and with three-step PWM all in stationary (a,b,c) reference frame, as well as average-current control in rotating (d,q) reference frame with zero-sequence-signal (ZSS) injection-based PWM and with space vector modulation (SVM). It is shown that the average-current control with three independent controllers exhibits the lowest total harmonic distortion (THD) of input currents, whereas, the average-current control in the rotating (d,q) reference frame with ZSS injection-based PWM and SVM exhibit the highest power factor. It is also shown that the average-current control with three independent controllers requires the shortest calculation time. The measurements were performed on a 3-kW, three-phase, six-switch, boost PFC rectifier prototype controlled by the TMS320F2808 DSP from TI.
